RESERVE-TANK VALVE.

Application filed. July 25, 1923.

To aZZ whom it may concern:

Be it known that I, VVILLLAM GUY WALL, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Reserve-Tank Valves, of which the following is a specification.

My said invention relates to a reserve tank valve intended particularly for use with fuel tanks of internal combustion engines. As is well-known it frequently occurs that the fuel in the tank of an automobile or motor boat becomes exhausted at '1 distance from any source of supply even where such tanks are provided with warningsignals or gages and the principal object of this device is to provide means for giving an unmistakable signal whenever the supply of fuel becomes low in that the supply to the engine is cut off while a considerable reserve supply remains.

A further object of the invention is to provide convenient means for making available the reserve supply when failure of the main supply is indicated.

Referring to the accompanying drawings, which are made a part hereof and on which similar reference characters indicate similar parts, i

The figure is a section of a tank with the valve of my invention applied thereto.

In the drawings reference character 10 indicates the walls of a fuel tank which may be of any size and form, preferably such as is used in connection with internal combustion engines. At the lower side of the tank is a nipple 11 having threaded connection with the tank or with a boss 12 secured thereto. The nipple is threaded at its lower end for connection to a gas pipe leading to the carbureter or other analogous device and at its upper end has an integral sleeve 13 with perforations at 14 close to the bottom of the tank. The sleeve 13 has at its lower end a tapering seat for a tapered valve 15 and a spring 16 within the sleeve rests at one end on a shoulder on the valve 15 and at its other end against a collar 17 held in place by pins 18 extending crosswise of the sleeve or it may be secured in any other convenient manner. The neck of the valve has a pair of transverse passages 19 communicating with a central chamber reduced in size at Serial No. 653,786.

its upper end to provide a shoulder abutting against an enlarged head on a rod 20. At its upper end the rod has a fixed collar 21 and a spring 22 surrounding the rod bears at one end against the collar and at the other end against a plate 23 fixed to the wall of the tank, packing 24 being provided between the plate and the wall to prevent leakage.

The rod 20 extends up through the plate 23 and the wall of the tank and carries at its upper end an operating handle 25 eccentric at one end. A wear plate 26 is secured to the wall 10 underneath the eccentric end of the lever 25.

In the operation of my device the parts are normally in the position indicated in the figure and may remain so until the fuel level reaches the plane of the top of the sleeve. During this time the fuel flows in at the top of the sleeve down through the same and through the passages 19 into the central chamber of the valve and so into the nipple and the gas line attached thereto. When the fuel reaches the plane indicated the supply to the engine will be cut off and it is necessary then to manipulate the lever 25. This lever being moved to the extreme upper position raises the rod 20 and holds it in position aganist the tension of springs 22 and 16. This opens the. waythrough passages 14 to the central passage of the nipple and the engine may continue to run until a filling station is reached or in the case of stationary engines until a supply of fuel can be brought.

\Vhen the tank is refilled the handle 25 is turned back to the position shown whereupon the spring 22 returns the rod to its lowermost position and the spring 16 returns the valve to place. The rod 20 is provided of a length sufficient to extend slightly into the valve in order to permit relative motion or lost motion between the rod and the valve for convenience in manufacture and repair and also to provide for a slight amount of wear between the valve and its seat.

Having thus fully described my said invention. what I claim as new and desire to secure by Letters Patent, is:

1. A reserve tank valve comprising a sleeve extending upward from the bottom of a fuel tank, said sleeve having bores of dif- .ferent diameters joined by an annular inclined surface forming a valve seat, passages sleeve e'irtend-i n g upward fronrthe-bottomof' "a fuel tank, said sleeve llzI-Vlllg'dJOl'GS of diflit through the sleeve-intermediate theends of: said annular inclined'surfaee,a hollow valvenormally closing said passages, passagesthi'iongh thevalveecommunicating with the top ofthesleeve, and-meansfor unseating the valve when the supply in the tank falls below the top of the sleeve, substantially as.-
